Application February 26, 1947, Serial No. 731,010

This invention relates to a detachable bracket connected to each other and separated from each other. Eachof said molding forms has a main longitudinal wall which is integral at its respective vertical edges with two respective transverse walls, which transverse walls are respectively integralwith two inwardly bent longitudinal flanges. The Y transverse walls have horizontal boresspaced at suitable intervals and arranged to form registering pairs when a pair of said molding forms are disposed adjacent each other with their respective transverse walls in abutting relationship. Fastening members ar insertable within registering pairs of bores in the abutting, transverse walls for detachably securing together adjacent molding forms. In molding a building unit it is customary to set up two opposed series of assembled molding forms and to pour the concrete or other building material into the predetermined space between said opposed series of assembled molding forms. In order to maintain the predetermined distance between the two 3 Claims. (Cl. 25-131) the accompanying drawing illustrating a preferred embodiment of the invention, and where- Fig. 1 is a fragmentary horizontal sectional I view illustrating a supporting bracket embody ing the features of the invention associated with an assembled pair of adjacent molding forms.

Fig. 2 is a perspective view of an assembled pair of adjacent molding forms with the. supporting bracket secured in position and with an angularly inclined supporting beam secured to the outwardly projecting wall of the supporting bracket. :5 Referring now to the drawing in detail, there are shown channel-shaped molding v forms I, each of which-has a main longitudinal wall l0 which is integral at its respective vertical edges with two respective-transverse walls 2, which are respectively integral with two inwardly bent and longitudinal flanges l l. Transverse walls 2 have horizontal bores l2 spaced at suitable intervals and arranged to form registering pairs when a pair of molding forms l are disposed adjacent each other with their respective transverse walls 2 in abutting relationship. Molding forms I may be detachably connected together by means of backing members L, each having a slotted or looped shank and an enlarged head La, said locking members being passed through each pair ssmbled molding forms under the weight of the molding forms, thereby eliminating a separate operation; and which may be secured in operative position without employing any fastening means other than the fastening member normally used to detachably secure adjacent molding forms together.

Additional objects and advantages of the invention will readily appear in the course of the following description taken in connection with of registering bores l2. In order to obtain a. tight, abutting relation between respective adjacent transverse walls 2 of respective molding forms I, wedges W are forced into each slotted or looped shank of each locking member L.

Each unitary supporting bracket 5 has a crosssection corresponding to the cross-section of the molding forms I which in the particular embodiments illustrated, is channel-shaped or U-shaped. Accordingly, the supporting bracket 5 has a main wall t which is integral at its respective vertical edges with two end-walls 1, said endwalls 1 being substantially perpendicular to said main wall 4. One of said end-walls l is inte gral with an outwardly projecting transverse wall 8 which is substantially parallel to main wall 4. Main wall 4 has a preferably centrally located horizontal bore l2.

It is thus seen that bracket 5 is shaped and dimensioned to fit within the channel of molding. unit I defined by longitudinal flange ll, transverse wall 2 and main longitudinal wall [0 and that said bracket 5 may easily be adjusted into position with its bore I2 in registration with a selected registering pair of bores 12 in respective adjacent transverse walls 2 of moldtionally to detachably secure supporting bracket l 5 in adjusted position within the channel of one of said molding forms with inner end-wall I flush against the inner surface of main wall H1. main wall 4 flush against the inner surface of transverse wall 2, outer end wall 7 flush against the inner surface of longitudinal flange II and projecting wall 8 extending outwardly from said molding forms, as illustrated in Figs. 1 and 2.

A fragment of temporary auxiliary frame-- work for holding molding forms I in place and comprising pairs of horizontal beams 3 is illustrated in Fig. 2. Angularly inclined supporting beams 3a may be fastened to outwardly projecting wall 8 of supporting bracket 5 by means of screws 6 or in any other suitable manner.

The particular shape and cross-section of the supporting bracket 5 may be varied to correspond to the particular shape and cross-section of the molding forms with which said bracket is to be associated.

I Since certain additional modifications may be made in the supporting bracket of my invention without departing from the scope thereof, it is intended that all matter contained in the'foregoing description and shown in the accompanyin drawing be interpreted merely as illustrative and not in a limiting sense.

I claim:

1. A mold comprising a pair of channel-shaped mold-sections, each said mold-section having an outer section wall which is fixed to respective end transverse section walls to which inner section walls are respectively fixed, said mold-sections being positioned with respective transverse section walls abutting each other and being connected to each other, said outer section walls being in alinement and said inner section walls being in alinement, a bracket which has a transverse bracket Wall which abuts and is connected tofa transverse section wall of a respective moldsection, said transverse bracket wall being fixed to additional outer and inner lateral bracket walls which abut the respective inner faces of the outer section wall and an inner section Wall of said respective mold-section, said inner bracket Wall having a transversely extending end-Wall which extends beyond said inner. section-walls. 2. A mold according to claim 1, in which said section walls are vertical, said bracket end-wall has a top horizontal edge and a supporting beam fixed to said bracket end-wall on said horizontal edge.

3. A mold according to claim 2, in which a supporting arm is secured to a face of said bracket end-Wall.
